Automate uploading new on-premises medical images to Cloud Storage for archival. What should you do?

The most straightforward and automated solution for regularly transferring on-premises data to Cloud Storage for archival is to use a scheduled script. The gcloud storage rsync command efficiently synchronizes directories, only transferring new or changed files, making it ideal for this use case. Scheduling this script as a cron job ensures regular, automated uploads without manual intervention. The other options are less suitable: Pub/Sub with an application publishing images is overly complex for a simple file transfer and requires building and maintaining a custom application. Pub/Sub with a Cloud Function is also overly complex and introduces unnecessary latency and cost for a bulk archival task; Cloud Functions are better suited for event-driven processing of individual objects rather than bulk synchronization. Manually uploading images is not an automated solution and is impractical for ongoing archival.
